SRAM’s PC-991 Chain delivers light weight, strength, quick shifting and smoothness to your drivetrain. It boasts chrome-hardened pins and inner and outer sideplates engineered to speed and smooth shifting in all conditions. And, with its great PowerLink, you don’t even need tools to install it.

SRAM’s premier 10-speed chain features hollow pins and cut-out outer plates for accurate shifting in all conditions, light weight, strength and smoothness. Plus, it's compatible with all industry-standard 10-speed systems. And, with its great PowerLock connecting link, installation and removal is a snap.

With SRAM's X1 Chain, it's 1x11 all the time, so the chain can be narrower, stronger, faster — all because it doesn't have to deal with high-stress, front chainring shifting. Since it only has to do rear shifts, gear changes are telepathically fast and feathery light. Its "wide tooth, narrow tooth" pattern perfectly matches SRAM's X-Sync chainrings so dropped chains and cumbersome chainguides are a distant memory. The durability is impressive, too, with SRAM's Hard Chrome tech, solid pins and a proprietary link finish for improved life span.

Traditional chain pins are 3mm in diameter. The Key Chains are 5mm, and they are available with a hollow or solid pin assembly. These oversized pins are 4 times stronger than traditional pins, and the chances of bending one, whether the pin is hollow or solid, are essentially zero. The 5mm riveted pins provide added strength, but they also provide a bigger contact surface with the chain’s plates, which makes them harder to push out or bend. The hollow pin assembly, by design, allows for a stronger rivet connection to form during manufacturing, resulting in a stronger chain overall. Each plate has a low profile and an extra narrow waist that makes it harder to catch the plates at unwanted times. At 1.4mm, the plates are substantially thicker than the plates of any other chain, and they’re also more than 50% harder to bend than the thickest existing 1.2mm chain plates too. Users can break and re-join the chain with just a 3mm hex key. The chain’s half link plates are taller at the bends to both increase stiffness and minimize stretch. Since the use of a chain breaker to re-join the chain has been eliminated, the pins can retain their original level of tightness from the factory. Also, carrying a spare master link and 3mm allen key in most cases is enough to repair the Key Chain when riding, so lugging around a chain tool is usually unnecessary. By using material as efficiently as possible, Odyssey has strengthened every component of the chain and kept the weight in the same range as their Bluebird chain. Stretching of the chain is minimized by using a standard alternating plate pattern and limiting the chain to a single, beefed up half link. This configuration maximizes the lifespan of the sprocket and driver. - Width: 1/8-inch
